hey guys i have bought some new speakers for the ralliart and wondering wat is the best amp to use? the speakers are eclipse sc8365 3-way speakers.
had a look at the eclipse site and some old posts. so would the xa200 2ch be enough? any other sugestions? but want to keep all eclipse.
thanks.

Why do you want to keep it all eclipse?
Hacing the same branded things wont give you any benefit unless you're being sponsored by them :doubt:

depends on how much you wanna spend really?
also if you want a amp for just the fronts? or all the speakers
if you only want to amp the fronts then the XA2000 would be the way to go
for all the speakers, the XA4000 would be the best one to go for
theres acouple cheap on ebay atm

yeah i did see those on ebay! wat would be best? the rears are only stock speakers, would it make much difference them running off the amp? cos there is not much price differance in amps?

if it was me, i would get the XA4000 amp
im thinking about getting one lol
has more power then the XA2000 which is good if you plan to upgrade later but mainly you can turn the gains down so the amp doesnt work as hard
any speakers will sound different (better) running off an amp instead of the h/u

yeah thought that would be the case! cheers mate!
the only other thing you could get 2 of the xa2000 for the same price! would that be better?? sorry bout the silly q's but i dont really now to much bout this stuff!
cheers

nah mate the XA4000 would be the best bet
its still better then 2 XA2000 cause the XA2000 is 2x100watts rms and the XA4000 is 4x125watts rms

I just bought a Kicker ZX 650.4 4x120 RMS amp today. Its tits.
Mind you, at a nudge under $650 retail (I got it $450) Its pricey. But oh my gawd the powerz.
Edit: If you're gonna go 4 channel and amp the rears, better look at some new ones. You'll blow the stockies.

this is the details on web site! wat is the difference between 4 ohms and 2ohms?? wat does this mean?? why do you get more power out of the one in brackets?
4-channel car amplifier
125 watts RMS x 4 at 4 ohms (175 watts RMS x 4 at 2 ohms)
350 watts RMS x 2 bridged output at 4 ohms
variable high-pass filter (30-500 Hz, 18 dB/octave)

2 ohms means there is the half the resistance for current than 4 ohms, yielding higher power output.
If you wire speakers in parallel to run at 2 ohms, expect to blow them out unless they are high end speakers. 175 RMS is some serious power, and you turn the gains up and you are just gonna blow the speakers.
Just run them in series (ie. + to +, - to -) and you'll be fine.

I'm a noob at this too - but isn't + to + parallel rather than series?

The noob is correct :bowrofl: ( BlackAWD ). +ive to +ive would be parallel and would mean that 2x 4ohm coils would run at 2ohm.
If you decide to get the 4ch amp, easiest way to hook it up would be the front channels 1 and 2 would run your spilts and the rear channels would run the rears or a sub. You must remember that you will lose power via the passive xover as well. To much power is never a bad thing, that is what the gain dial is for. I have run 40WRMS speakers with a 150WRMS amp. No problems, just be sensable on the volume and gains dial.
If you wanna get a bit more serious, you should look at the xover point on your xover for the LP on the mid. If it is on or under 500Hz you could:
Run the woofers off channel 3 and 4 LP @ 500Hz on the amp - HP them off the headunit ( effectively bandpassing the woofers ).
Run the mids and tweeters through the passive xovers they provide of channels 1 and 2. Amp would be set to bypass or HP @ 500Hz. Only a thought for potentially a 250WRMS per side front stage. :D
